Transgressive Body, Open Mind, And Perceptive Spirit For Nurturing Soul: A Reflection On Teaching To Transgress, Akie F. Wenk

Journal of Communication Pedagogy

In this reflection essay, I discuss my journey into the liberatory pedagogy bell hooks champions. As a foreign-born Japanese woman, who speaks English as her second language, being in the classroom itself can be seen as a transgressive act. Positioning myself as an educator who strives to creates an environment that is liberatory for me and my students, I discuss my specific experience and relationship to theories surrounding critical feminist pedagogy and how I practice these theories in my own classroom.

Objectives: To determine the impact of virtual group coaching to enhance occupational performance, satisfaction, self-efficacy and relationship closeness in people living with SCI.

Methods: A quasi-experimental single-group pre/post-test design was used. Adults with SCI were recruited through online flyers, social media, newsletters, support groups, clinics, …

Correlation Measures In Metagenomic Data: The Blessing Of Dimensionality, Alessandro Fuschi, Alessandra Merlotti, Thi Dong Binh Tran, Hoan Nguyen, George M. Weinstock

Faculty Research 2025

Microbiome analysis has revolutionized our understanding of various biological processes, spanning human health and epidemiology (including antimicrobial resistance and hor- izontal gene transfer), as well as environmental and agricultural studies. At the heart of microbiome analysis lies the characterization of microbial communities through the quantification of microbial taxa and their dynamics. In the study of bacterial abundances, it is becoming more relevant to consider their relationship, to embed these data in the framework of network theory, allowing characterization of features like node relevance, pathways, and community structure. In this study, we address the primary biases encoun- tered in reconstructing networks …

The Efficacy Of Virtual Group Coaching On The Self-Determination Of People With Ehlers-Danlos Syndrome, Janine E. Rajauski, Ms, Otr/L

Post-Professional Occupational Therapy Doctorate Culminating Presentations

INTRODUCTION
The Ehlers-Danlos Syndromes (EDS) are a family of 13 genetic connective tissue disorders that affect negatively physical and psychosocial health which in turns have been found to decrease their quality of life and self-determination (Baeza-Velasco et al., 2019; Bennet et al., 2021; Estrella & Fraizer, 2024; Tinkle et al., 2017; Palomo-Toucedo et al., 2020). Limited supports and services, including occupational therapy, are available for those with EDS (Estrella & Frazier, 2024; McDonald et al., 2023; Reychler et al., 2021). Those with EDS have requested better services to support their self-determination (Estrella & Frazier, 2024). Coaching has shown positive impacts …

Limited research has examined how caregivers perceive the factors shaping these decisions, particularly in the United States context. This mixed-methods cross-sectional study explored how caregivers in the St. Louis, Missouri metropolitan area perceive the socio-ecological factors shaping their attitudes toward risky outdoor play for children aged 13 to 47 months with developmental delays or disabilities. The project sought to first explore caregivers' perceptions of how interpersonal and individual factors, shape …

Enhanced Nanomechanical, Tribological And Electrical Properties Of Ni-Cr Coatings Via Max Phase Reinforcement And Metallic Interlayers, Mohammad Ashikul Alam

Theses and Dissertations

Nickel-Chromium (Ni-Cr) coatings are widely used in industrial applications due to their resistance to oxidation, thermal stability, and adjustable electrical and mechanical properties. However, achieving improved multifunctional performance across various use cases ranging from extreme tribological environments to microscale device integration remains a significant challenge. This thesis explores two complementary strategies for enhancing the performance of Ni-Cr coatings in both thick and thin film configurations, aiming to address limitations in wear resistance, durability, adhesion, and electrical conductivity. For thick coatings, Ni-Cr was reinforced with Ti3SiC2 MAX phase particles and processed using selective laser sintering (SLS) with optimized parameters. The addition …

Beyond The Individual: Community Socioecological Correlates Of Mass Shootings In A Cross-Sectional Analysis, Barbara (Basia) E. Lopez

Walden Dissertations and Doctoral Studies

Mass shootings represent an urgent and persistent threat to public safety in the United States, yet most research has focused on individual-level characteristics, leaving community-level socioecological conditions comparatively underexamined. This study addressed this gap in knowledge through an examination of the statistical correlations between community-level characteristics and mass shooting incidence using Ostrom’s social-ecological systems theory as a guiding framework. A cross-sectional quantitative design was employed using secondary data from The Violence Project, the U.S. Census Bureau, Neighborhood Atlas National Data Archive, and publicly available law enforcement and policy records. Multiple regression analysis was performed to test both main and interaction …

Walden Dissertations and Doctoral Studies

The aim of this doctor of nursing practice staff education project was to provide a staff education program to the same day surgery staff at the practicum site on the Enhanced Recovery After Surgery (ERAS) evidence-based approach to surgical care to improve patient outcomes. ERAS includes multiple modalities designed to optimize a patient’s condition before, during, and after surgery. When implemented correctly, ERAS can reduce the need for narcotics, shorten recovery time, and improve surgical outcomes. The practice gap identified was that the only ERAS modality being actively implemented and tracked was nutrition in colorectal surgical patients and that the …

Lived Experiences Of Police Officers With Vicarious Sexual Trauma, Resiliency, And Departmental Support, Joseph Schreiner

Walden Dissertations and Doctoral Studies

This qualitative study involved addressing lived experiences of police officers who investigate sex crimes. Vicarious sexual trauma experienced by officers can lead to both short- and long-term issues for these individuals, particularly if they are left unaddressed. The constructivist self-development and resiliency theories were used to examine these experiences. Specifically, this study involved investigating how police officers perceived vicarious sexual trauma and viewed the accessibility and practicality of mental health and wellness resources provided by their departments. It was guided by two research questions, which were addressed through 12 semistructured interviews, which were thematically analyzed and interpreted. Five themes emerged …

Coloring Outside The Lines: Factors Facilitating Divergent Thinking, Michelle Baca Reinke

Master's Theses

Divergent thinking involves producing a multitude of unique and diverse ideas. The ability to “color outside the lines” is crucial to business, education, and social domains. The flexibility, originality, and fluency dimensions of divergent thinking are commonly assessed using the Alternative Uses Task, which involves generating uses for common objects. Prior research suggests that high identification (first-person perspective) with schema-inconsistent experiences increases flexibility, while semantic density (degree of conceptual associations) impacts originality and fluency inversely. However, their combined effects across multiple divergent thinking dimensions remain unexplored. The present research investigated the interactive effects of identification (high, low), schema consistency (consistent, …

How People With Borderline Personality Disorder Experience Addiction During The Process Of Treatment, Michael Paul Onesto

Walden Dissertations and Doctoral Studies

This study explored the lived experience of Borderline Personality Disorder (BPD) and substance use as a maladaptive coping mechanism during recovery, raising the question of whether recovery itself fosters comorbidity. The study was grounded on several theories, including Linehan’s biosocial model, the Cox and Klinger alcohol motivation model, the affect regulation model, and the self-medication hypothesis. These theories argue that substance use arises from emotional vulnerability, invalidating environment, and affect regulation efforts. The study employed a phenomenological qualitative approach to guide data collection and analysis. Interviews from 20 BPD patients and mental health care providers were completed. The thematic analysis …

The Treatment Experiences Of Female Domestic Violence Offenders Who Have Completed Court-Mandated Counseling Programs, Chelsea S. King

Walden Dissertations and Doctoral Studies

Domestic violence is a significant societal problem. However, aspects of domestic violence (DV) perpetrated by women are often overlooked or inadequately addressed in existing counseling and intervention programs, leaving counselor educators ill-equipped to effectively train counselors to treat this specific population. The research question addressed the treatment experiences of female DV offenders who completed court-mandated counseling programs. Given the limited current research on female domestic violence offender treatment, Heidegger’s hermeneutic phenomenological methodology was employed to further understand the perspectives of participants, potentially identifying areas of improvement and addressing the needs of female program participants. Semistructured interviews were completed with six …

The Lived Experience Of The Orgasm Gap In U.S. Cisgender Women In Heterosexual Relationships, Alina Beverly Vergara-Hegi

Walden Dissertations and Doctoral Studies

Women are not orgasming as often as men in heterosexual sexual encounters. Research has confirmed that sociocultural influences, gender differences, sexual perceptions, sexual miseducation, and relationship dynamics contribute to women’s negative sexual experiences. What has been missing is a better understanding of the experience of the orgasm gap and the role of gender ideology in women’s sexual experiences. This study explored the lived experience of the orgasm gap and gender ideology in nine cisgender women in long-term heterosexual relationships. Critical feminist theory was used as the lens to explore the meaning of sexual inequities in intimate long-term relationships. Using interpretative …
